(CRAED) AED Automated External Defibrillator Lesson

AED Automated External Defibrillator Lesson

Defibrillation is an essential part of resuscitation. Should a victim be in cardiac arrest and require defibrillation, it is crucial that EMS is called immediately.

Step 1

To begin Defibrillation operations, start by exposing the chest, and removing all metallic items (jewelry, nipple piercings, etc.). It is also crucial that you remove any patches (especially medicine and nicotine) on the person's chest while wearing gloves to ensure the shock will not be interrupted by having to go through these patches. Failure to remove nicotine patches can result in a fire.

Do Not Shock If....Image

--The victim is close to explosive or flammable material.
--The victim is wet. Dry the victim off with a towel.
--The victim has a medicine patch on them. You must remove this while wearing gloves.
--The victim is touching in an object that could conduct the charge to others. For example, a metal bench.

Cell phones and other electronic devices can disrupt the analyzing phase of the AED. Check for a cell phone on the patient and remove it to a distance of 6 feet or more. This will include your cell phone and any bystander who is carrying one. (If time is crucial, throw the cell phone as far as possible, don't take precious seconds to walk it somewhere. Remember, life over limb (or possessions, in this case.)

Step 2

Now turn on the defibrillator unless it automatically turns on once you open it. Most AED units will give clear voice instructions; follow the prompts. Once the chest is exposed, you are to place the electrodes: one on the left side, under the arm, and the other over the right breast. The location of pad placement is clearly depicted on each pad; they must go exactly as shown in the picture. Once connected, the defibrillator will automatically start monitoring the heart's electrical activity to determine whether a shock is appropriate. Some defibrillators require the user to press an analyze button before the machine will analyze the heart rhythm. The machine will clearly talk you through all steps of the process.

CPR must be stopped while the defibrillator is monitoring the victim's heart activity. In all cases, defibrillation has priority over CPR. Do not touch the victim or the AED - if you do, you could interfere with the analysis.

Step 3

If the AED advises a shock, the operator will say "I'm Clear, you're clear, we're all clear" while ensuring that the operator is not touching the victim or standing in a wet environment next to the victim that could conduct electricity through the rescuer. The AED operator is also making sure that all other people surrounding the victim are clear. The final "we are all clear" ensures a double check to ensure that everyone is away from the victim. If the victim is being given oxygen supplementation, the equipment must be removed at this point. The AED will shock the victim; the operator may be required to press a shock button. Touching the victim is potentially fatal when the shock is administrated. After the shock has been delivered, it is safe to touch the victim; no electricity will remain in them. The defibrillator will advise you what to do next - usually you'll be told to begin chest compressions and rescue breaths again.
